Specification of Letters Patent. pat gntgfl June 25,, 191$ Application filed July 24, 1916. seria no. 110,876.

To all fwhom it may concern I Be it known that I, EMIL O. TECKTONIUS,

a citizen of the United States,\residing at had to the accompanying drawing, forming a part thereof.

This invention relates to hoop or band lugs for tanks, kilns, silos and similar, structures and the objects of the invention are to improve such lugs in the manner to be hereinafter described and claimed.

Referring to the drawings which accompany this specification and form a part hereof, which drawings illustrate an embodiment of this invention and on which drawings the same reference characters are used to designate the same parts wherever they may appear in each of the several views, Figure l is an elevation of the lug and associated parts; Fig. 2 is a vertical, longitudinal section of the lug, showing the asso ciated parts in their operative positions; and

Fig. 3 is a plan View of the lug and associated parts.

Referring to the drawings, the reference numeral 1 designates a tank, kiln, silo or similar structure, parts of which are held in place or strengthened by hoops or hands. A hoop may be composed of a single section or a plurality of sections, depending upon 7 the size of the structure with which it is to be used or the preference or convenience of the user. For the sake of simplicity of description it will be assumed that the hoop illustrated by the drawings is composed of a plurality of sections which are of identical construction and which are connected by lugs of identical construction. 7

One end of a hoop or hoop section "is constructed to engage with a lug 8 and the other end is screwthreaded to receive a nut 5. These featuresof construction are illustrated by the drawings, the hoopv section 2 being shownas provided with the head 4 and a nut 5 being shown on the screwthreaded end of the hoop section 6.

For the sake of lightness and to save material while providing for the proper distribution of the metal to withstand the strains to which these lugs are subjected, the lug 18 made as an integral casting in. a skele-.

ton form and comprises the side walls 7 and 8 which areninited by the froiit wall 9,the rear Wall 10, the arch 11 and the webs 12" and The front wall 9 is'provided with an aperture 14 which is large enouglrto freely receive the hoop section 2 at slightlydifferent angles to accommodate the'positions of the parts to structures of different sizes. The lug serves as an anchorage for one end Qfthe hoop while the other end of the hoop strains against the lug. The rear wall .10 is provided with an aperture 15 which is large enoughto permit the hoop section 6 to pass freely therethrough and which is elongated in the direction of a diameterof the structure to which the hoop is to be applied, as clearly illustrated by Fig. 2 of the drawings, to permit the hoop section 6 to pass through said aperture at different distances from the base of the lug so that the end of the hoop section. can be tangent to the structure whatever its size may be within the limits of movement provided for.

The contacting edges of the side walls 7 and 8, or the base of the lug, are preferably suitably shaped to fit snugly against the sur face or surfaces to which they are to be applied to prevent any tendency to tip or rock upon such surface or surfaces and they may be headed or otherwise enlarged to afi'ord enlarged bearing surfaces. 1

Spiral springs 16, of the open or compression type,.are placed 011 the screwthreaded ends of the hoops or hoop sections and can be compressed by nuts 5 against the rear wall 10 to exert the required tension upon the hoops. Eveners l7 and 18 are preferably placed between the springs and nuts and rear walls 10, as shown by the drawings. The arch 11 connects the side walls 7 and 8 at a point between the front wall 9 and the rear wall 10 and is considerably nearer the front wall than the rear wall. This arch not only braces the side walls but in conjunction with the front wall forms an aperture through which the spring 16 andfithe screwthreaded end of the hoop section 6 project. This aperture is slightly larger than the spring 16 and, while retaining the spring and hoop section in nearly a fixed position, permits the hoop section to occupy different positions in the aperture 15 in the rear wall 10, according to the size of the structure around which a hoop is placed, so that the screwthreaded end of a hoop section can lie in the line of a tangent to the structure and by screwing up a nut 5 the hoop section can be pulled directly through the lug without being bent over or through the lug whereby all the force applied by the nut 5 is exerted in pulling the hoop tight around the structure. The function of the spring 16 is to permit the structure to expand without in jury and to keep the hoop tight when the structure contracts, and the spring can readily pull the hoop through the lug because the hoop is not bent in passing through the lug.

What is claimed is: I g

An integral hoop or band lug fortanks or similar structures composed of side walls,

front andrear walls and an arch connecting the side walls between the front and rear walls; the rear wall being providedwith an aperture elongated in the direction of a diameter of a tank or similar structure and wide enough to freely receive a hoop or band so thatthe rear wall serves as an abut- I C o pies of this patent'may be obtained for ment for a spring surrounding a hoop or band to take the entire strain put upon the hoop or band an aperture being provided between the front wall and the arch through which the end of the hoop or band, with the spring surrounding the same, can freely pass in a line tangent to the structure to which the lug is applied although the hoop or band may pass through the elongated aperture in the rear wall at different disstances from the structures to. which the lug may be applied depending upon the sizes or diameters of the structures, and the front wall beingprovided with an aperture in a line with the elongated aperture in the rear wall to receive the stationary end of a hoop or-band.

In witness. whereof I hereunto afiix my signature.

EMIL C. TECKTONIUS.
